MAXREFDES1226: Small, low-profile, 5V/1.5A, synchronous, optocouplerless flyback DC-DC converter with efficiency as low as 87% with the MAX17690 and MAX17606

Due to its simplicity and low cost, the flyback converter is the preferred choice for low-to-medium isolated DC-DC power-conversion applications. However, the use of an optocoupler or an auxiliary winding on the flyback transformer for voltage feedback across the isolation barrier increases the number of components and design complexity. The MAX17690 eliminates the need for an optocoupler or auxiliary transformer winding and achieves ±5% output voltage regulation over line, load, and temperature variations.

5V 1A, low EMI, 94% efficiency DC/DC module reference design using double-layer TO-220 package

TI reference design TIDA-00946 demonstrates a 10.5mmx14.5mm, 94% efficient low electromagnetic interference (EMI) DC/DC module using the TPS54202, replacing low dropout regulators (LDOs) in most appliance applications. High efficiency eliminates the need for a heat sink, resulting in a smaller, lower cost solution. Higher current capacity enables the addition of more functionality (WiFi, sensors, etc.). High efficiency and low current consumption help achieve stringent energy efficiency ratings.
